T0 or. whom it may concern:

Be it known that I, WILLIAM H. WALLACE, a citizen of the United States,and a resident of Whitefield, near Henry, in the county of Marshall andState of Illinois, have invented a new and Improved Coupling, of whichthe fol lowing is a full, clear, and exact description. This inventionrelates to improvements in couplings particularly designed for use inconnection with traction-engines for coupling the same to tenders,agricultural implements, threshing machines, and other wheeled devices,an object being to provide a coupling of simple construction that may bereadily attached to a traction-engine and that will be Very strong anddurable.

I will describe a coupling embodying my invention and then point out thenovel features in the appended claims. I

Reference is to be had to the accompanying drawings, forming a part ofthis specification, in which similar characters of reference indicatecorresponding parts in all the figures.

Figure 1 is a side elevation of a portion of a traction-engine and acoupler embodying my invention attached thereto. Fig. 2 is an invertedplan View thereof. Fig. 3 is a section on the line as w of Fig. 2,- andFig. 4 shows a tongue and a supporting device therefor with a member ofthe coupling attached to the tongue.

Referring to the drawings, 1 designates the platform of atraction-engine, and arranged underneath the platform is a draw-bar 2,on the outer end of which is a coupling-head 3, supported and movable ina hanger 3". The draw-bar 2 extends through an opening in a hanger 4,bolted or otherwise secured to the has an upper wall 9 and a lower wall10, these members being spaced apart to receive a linklikecoupling-section 11, attached to a tongue lugs 24 on the tongue.

or pole 12 of the device to be drawn. Mounted to swing in thecoupling-head 3 is a lever 13, having a hook portion 14, with which thelink 11 is designed to engage. This hook portion 14 is inclined downwardand forward, and

above said hook portion is an upwardly-ex tended horn 15, movable in anopening formed 'in the top wall 9 of the coupling-head. The

lever 13 is mounted on a shaft 16, having bearings in the side walls ofthe coupling-head, and on one end of this shaft is a crank 17, fromwhich a rod'l8 extends to a lever 19, pivoted in lugs 20, attached totheunder side of the platform 1. This lever 19 extends above the platform,so that the driver of the engine may operate the lever to release thecoupling by foot-pressure.

From the hanger 4 brace-rods 21 extend rearward and are connected tobrackets 22, attached to the under side of the platform:

To hold the tongue 12 in position to engage the link 11 with the hookportion 14, I employ a standard 23, mounted to swing between Thisstandard has an enlarged bearing end 25 to engage upon the ground, andwhen the support is not in use for holding the tongue in position it maybe swung upward and engaged between springclips 26, attached to thetongue.

In some instances, suchas when a tractionengine drawing a vehicle ispassing over rough ground or up or down hill, it is necessary to lockthe coupling member 13 in its coupled position. For this purpose Iprovide a lockingrod 27, which is substantially L-shaped .and designedto pass between the upper edge of the lever 13 and the inner side of thetop member 9 of the coupling, this top member 9 being provided at itsunder side with a channel 28, into which the horizontally-disposedmember of the locking device may pass. This locking device is attachedto the engine by means of a chain 29, and it is held from accithe parts,as the hook will engage against the wall of said notch or depression. 7The outer end of the hook member is inclined downward and forward, sothat it will be automatically raised when the engine is moved backwardand the said curved end of the hook engaged with the member 11 of thecoupling. After said member 11 passes underneath the hook the said hookwill fall by gravity.

When it is desired to release the coupling, the driver of thetraction-engine by placing 'his foot on the upper end of the lever 19and pushing it forward will rock the shaft 16, moving the hook memberupward and out of engagernenuwith the member 11.

Having thus described my invention, I claim of a draw-bar yieldinglyconnected thereto, a.

coupling-head on the draw-bar, the said coupling head having upper andlower spaced members, a lever mounted to swing in the coupling-head, andhaving a downwardly and forwardly inclined hook member at its end, alink for engaging with said hook, a shaft on which the lever is mounted,the said shaft having bearings in the side walls of the coupling-head,means for rocking the lever upward, and a pin for locking the lever inits depressed position, the said pin having an outwardly-turned end forengaging with a side of the coupling-head.

3. The combination with a traction-engine, of a hanger attached to thelower side of the platform of the engine, the said hanger having anopening, a draw-bar movable through said opening, springs betweenopposite sides of the hanger. and parts on the draw-bar, bracerodsextended from the hanger to the platform, a coupling-head on thedraw-bar, a lever mounted to swing in said head, the said lever having ahook port-ion, a lever having swinging connection with the engine, and arod connection between said lever and the first-named ever.

4:. The combination with a traction-engine, of a coupling member, atongue or pole, a link-like coupling member attached to said tongue orpole for engaging with the coupling member on the engine, a standardhaving swinging connection with said tongue or pole, and spring-clipsfor holding said standard in position parallel with the tongue or pole.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.
